SPOT-LIGHT ATTACHMENT.

Specification of Letters Patent.

Application filed December 12, 1913.

Patented June 23, 1914. Serial No. 806,291.

The primary object of the invention is the provision of means wherebymoving picture mechanism, stereopticon and the like may be utilized inthe capacity of a spot light thereby overcoming the necessity forproviding a spot light apparatus and the cost incident to the purchaseand maintenance of such spot light mechanism.

The invention provides an attachment which may be readily applied to andused in connection with moving picture apparatus, stereopticons, magiclanterns and the like, whereby the same may be used in the capacity andfor the same purpose as the ordinary spot light to enable the performeror other object to be illuminated to the exclusion of the surroundings.

The invention provides an attachment of the nature and for the purposespecified which will not interfere with the ordinary use of the movingpicture apparatus, stereopticon or the like and which may be instantlybrought into service for projecting a spot light to any point upon amoving object, the attachment being such as to enable the spot light tofollow a moving object in any direction in precisely the same manner asthe usual spot light specially designed for such purpose.

The invention consists of the novel features, details of constructionand combination of parts, which hereinafter will be more particularlyset forth, illustrated in the accompanying drawings, and pointed out inthe appended claims.

Referring to the drawings, forming a part of the specification, Figure 1is a side View of a spot light attachment embodying the inventionshowing the same in connection with an ordinary moving pictureapparatus. Fig. 2 is a detail view showing the attachment with theprimary reflector moved to such a position as not to deflect the rays oflight. Fig. 3 is a view similar to Fig. 2 showing the primary reflectormoved to throw the rays of light upon the secondary reflector by meansof which the light beams are projected to throw the spot of light uponthe object to be illuminated. Fig. 4 is a detail view of the attachment.

Corresponding and like parts are referred to in the followingdescription, and indi cated in all the views of the drawings, by thesame reference characters.

The numeral 1 designates the lamp house of a moving picture apparatussuch as in general use.

The numeral 2 indicates the usual stereopticon lens and 3 the ordinarysupporting rod therefor. Inasmuch as the attachment is designed chieflyfor use in connection with moving picture apparatus it is illustrated inthis connection in the accompanying drawings but it is to be understoodthat it may be applied to any picture projecting apparatus such asstereopticons and magic lanterns, the attachment being located in frontof the usual stereopticon lens to admit of controlling the rays of lightto such an extent as to enable the operator to cause the spot to followa moving object.

The attachment comprises a frame 4 which is in the nature of a housingor casing. Two reflectors or mirrors 5 and 6 are located within theframe 4, the numeral 5 designating the primary reflector or mirror andthe numeral 6 the secondary reflector or mirror. The purpose of theprimary reflector or mirror 5 is to deflect the rays of light and throwthe same upon the secondary reflector or mirror 6. When the pictureprojecting apparatus is to be used in the ordinary way the reflector ormirror 5 is moved to a position so as not to obstruct the rays of lightwhich are projected in a straight line from the stereopticon lens orlike part to the screen. This is indicated most clearly in Fig. 2. Whenthe attachment is required for use to enable the beam of light from themoving picture apparatus to be controlled so as to follow a movingobject the mirror 5 6 is mounted to turn freely about both a verticaland a horizontal axis, such reflector being under the control of theoperator to enable the beam of light to be thrown so as to keep a movingobject in the light spot in substantially the same manner as theordinary light machine. A handle 7 is-connected with the mirror 5 and isadapted to engage either one of two stops 8 or 9 to hold the reflector 5in the path of the beam of light or out of such path so as not tointercept the rays of light. A handle 10 is connected with the reflectoror mirror 6 and enables-such mirror to be turned about a vertical and ahorizontal axis. A turntable 11 is mounted to turn about a vertical axis12 and the reflector or mirror 6 is pivoted thereto at 13 to turn abouta horizontal axis. The handle 10 has direct connection with the mirroror reflector 6- thereby enabling the same to be turned about either thehorizontal axis 13 or the vertical axis-12 whereby the spot light iscaused to follow the moving object in a manner well understood.

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains, and while we have described theprinciple of operation of the invention, together with the device whichwe now consider to be the best embodiment thGIQOZQWe desire to have itunderstood that the device shown is merely illustrative, and that suchchanges may be made when desired as are within the scope of the claimsappended hereto.

Having thus described the invention what a primary reflector pivotallymounted to be thrown into or out of the path of the beam of lightprojected by means of'the picture apparatus and a second reflectorarranged to receive the beam of light deflected by the primaryreflector. and mounted to turn about a vertical and a horizontal axistoadmit of the deflected beam of light to be thrown so as to follow amoving-object. a

2'. A spot light attachment for picture projecting apparatus-,. the vsamev comprising a frame, a primary reflector located within such frameand pivotally mounted so as to occupy a position either to clear thebeam of light projected from the picture appae ratus or to interceptsuch beam oflight, means for holding the primary reflector in theadjusted position and a second reflector mounted within the frame toturn about a vertical and a horizontal axis and under control of theoperator to enable the beam of light deflected by theprimary reflectorto be projected to follow. a moving object.

In testimony whereof we affix our signatures in presence oftwo-witnesses.
